# Unlocking large scale AI training networks with MRC (Multipath Reliable Connection)

# Claim

OpenAI introduces MRC (Multipath Reliable Connection), a new supercomputer networking protocol released via OCP to improve resilience and performance in large-scale AI training clusters.

# Relevance

Appendix III, section two: vendor threshold and platform capability evidence

# Oracle Verdict

This is a lower-to-mid strength vendor signal for the capability register. It does not prove displacement on its own, but it records another platform step that can later show up as workflow automation, procurement change, or organisational dependency.
